The following description is a specific embodiment of the present claims, and other specific implementations not explicitly described in connection with the claims also fall within the scope of the claims.
FIG. 1 shows a schematic diagram of a system for planning surface and subsurface facilities based on subsurface energy distribution.
As shown in fig. 1, a system for planning earth surface and underground facilities based on underground energy distribution comprises an information acquisition module 1, a first position determination module 2 and a second position determination module 3, wherein the information acquisition module 1 is used for acquiring type, position and reserve information of underground energy sources; the first position determining module 2 is configured to determine a position of a corresponding energy utilization facility according to the type, the position and the reserve information of the energy; the second position determining module 3 determines the positions of the surface and underground facilities according to the positions of the energy utilization facilities.
The information acquisition module 1 detects and acquires information of underground energy through seismic data acquisition, drilling information acquisition or other existing or future information acquisition technologies. The underground energy information is mainly obtained as an energy type that can affect the surface and underground facilities, and in this embodiment, three kinds of energy, geothermal energy, petroleum and natural gas are exemplified. However, oil and gas are sometimes in the same reservoir, and can be divided into two types.

The E is Loss = f (L) is a nonlinear relationship. The mapping relation f contains factors such as earth surface and underground state, geological structure and the like.
When the energy source is natural gas or petroleum, the method is also adopted to obtain the positions of various energy source utilization facilities, and different mapping relations are different, different influencing factors such as petroleum energy sources need to be added, and the pollution condition limitation needs to be added in the mapping relations.
After the locations of the above three energy utilization facilities are determined, planning of surface and underground facilities is required.
Taking a living business area as an example, the second location determining module 3 establishes a nonlinear equation relationship between the distance between the living business area and each energy utilization facility and the energy loss through consideration of various factors. Namely:
when the underground energy is geothermal, natural gas or petroleum, determining the positions of geothermal utilization facilities, natural gas utilization facilities and petroleum utilization facilities, and determining the positions of the living business areas by using the following formula;
wherein x represents the distance from the central point of the living business district to the geothermal utilization facility;

z represents the distance from the central point of the living business area to the petroleum utilization facility;
E 1 representing geothermal losses;
E 2 representing natural gas loss;
E 3 representing oil loss;
when the x, y, z takes on a value such that E 1 、E 2 And E is 3 And when the sum is minimum, the values of x, y and z are taken to determine the position of the life business district.
Wherein f 1 、f 2 、f 3 In the mapping relationship of (a), various influencing factors, such as the living business district needs to be far away from the pollution source and needs to be close to the geothermal utilization facility as much as possible so as to reduce the energy loss, etc., the invention is not limited.
According to the mode, the characteristics and the requirements of other earth surface and underground facilities needing planning are comprehensively considered, the interrelation between the distance between the earth surface and underground facilities and the energy utilization facilities and the energy loss is established, and the nonlinear equation is further formed, so that the relative positions of the earth surface and underground facilities are determined, and the planning of the earth surface and underground facilities is realized.
FIG. 2 shows a schematic diagram of method steps for planning surface and subsurface facilities based on subsurface energy distribution.
As shown in fig. 2, a method for planning earth surface and underground facilities based on underground energy distribution includes obtaining type, position and reserve information S1 of underground energy; determining the position S2 of the corresponding energy utilization facility according to the type, the position and the reserve information of the energy; the location of the surface and underground facilities is determined based on the location of the energy utilization facility S3.

For example, in a living business area, the demand for geothermal heating is large, the demand for natural gas is large, the pollution to various industries is brought, the ground surface and underground facilities are required to be far away, and the ground surface and underground facilities can be divided into the living business area.
According to one embodiment of the invention, the location of the energy utilization facility is determined according to the location information of the energy source;
setting a central point of mapping of the position of the energy source on the earth surface and the underground, wherein the distance between the energy source utilization facility and the central point is L, and the loss of exploiting the energy source is E Damage to Can obtain the correlation equation of the two, E Damage to =f (L), taking the value of L such that E Damage to And (3) obtaining the position of the energy utilization facility if the value of the energy utilization facility is minimum.
